| Abstract: | 3-dimensional eddy current problems can be divided as uncoupled electric and magnetic boundary value problems, and an approach of equivalent sources for magnetic field is presented. The selection and distribution of these equivalent sources are important for this method. The distribution of magnetic flux density of a conducting sphere in a uniform alternating magnetic field is computed. The results almost consistent with analytic solutions, and thus means the approach is efficient for solving 3-dimensional eddy current problems. |
